How to rotate something in photoshop timeline animation?

Hello all,

This may seem like an extremely amateurish question but today I've been having the hardest time making an animation of a person walking using keyframes in photoshop timeline animation. Basically, I want each leg component to rotate every time he takes a step, and for the position of the leg component to change as he's moving forward. Bottom line: I want to animate the rotation and position of a layer.

I set my keyframes up accordingly, and the position animated just fine, but I'm having serious trouble with the rotation. I move my ticker over the keyframe, hit ctrl+T, and rotate, but the rotation is applied to the entire animation and not just that keyframe. I'm so confused.

Then I tried, in the timeline panel, changing the motion from "custom" to "rotate", but the problem this time was that when i tried rotating it, it disregarded my anchor point no matter where I dragged it to and just rotated around the middle. Is it because I am trying to animate the rotation AND the position that's making it complicated?

Please help!
